Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 103,153,105, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 103,153,105 | |
| -1 | -103,153,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,153,105.
Example:
1 x 103,153,105 = 103,153,105
and
-1 x -103,153,105 = 103,153,105
Notice both answers equal 103,153,105
With that explanation out of the way, let's continue. Next, we take the number 103,153,105 and divide it by 2:
103,153,105 ÷ 2 = 51,576,552.5
If the quotient is a whole number, then 2 and 51,576,552.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,153,105 | |
| -1 | -103,153,105 |
Now, we try dividing 103,153,105 by 3:
103,153,105 ÷ 3 = 34,384,368.3333
If the quotient is a whole number, then 3 and 34,384,368.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,153,105 | |
| -1 | -103,153,105 |
Let's try dividing by 4:
103,153,105 ÷ 4 = 25,788,276.25
If the quotient is a whole number, then 4 and 25,788,276.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,153,105 | |
| -1 | 103,153,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 121 | 265 | 583 | 605 | 2,915 | 3,217 | 6,413 | 16,085 | 32,065 | 35,387 | 170,501 | 176,935 | 389,257 | 852,505 | 1,875,511 | 1,946,285 | 9,377,555 | 20,630,621 | 103,153,105 |
| -1 | -5 | -11 | -53 | -55 | -121 | -265 | -583 | -605 | -2,915 | -3,217 | -6,413 | -16,085 | -32,065 | -35,387 | -170,501 | -176,935 | -389,257 | -852,505 | -1,875,511 | -1,946,285 | -9,377,555 | -20,630,621 | -103,153,105 |
